SGE Syringe Valves

Push-Button with Kel-F male Luer lock termination

Syringe valves are ideal for sample storage and transportation or to pressurize samples prior to injection. SGE offers several types of manually-operated syringe valves: push-pull for smaller volumes (2.5 μL-2.5 mL) and push-button valves (50 μL-2 L). SGE Luer Tip, Luer Lock and removable needle syringes can be fitted with valves. The valve allows fluid to be stored in the syringe without contamination.
Cat. No. 509337 is a push-pull valve with removable 0.63 mm O.D. × 5 cm cone tip needle. This valve will fit removable needle syringes, 25μL-2.5mL.
Cat. No. 509345 is a push-pull with Kel-F male Luer lock termination to fit removable needle syringes, 25μL-2.5mL
Cat. No. 509353 is a push-button with Kel-F male Luer lock termination. This fits 5 mL to 2 liter syringes with removable Luer Lock or removable needle.
Cat. No. 509361 is a Luer Lock valve for any Luer Lock and Luer Tip syringe (50μl to 2 liter).

SGE syringe valves may be used with gas tight syringes, for introduction of samples to the gas sampling and injection system (GASIS) inlet, in an experimental study conducted for the analyses of compound-specific δD and δ¹³C gas mixtures using gas chromatography-oxidation/reduction-isotope ratio mass spectrometry.[1]
